The BioMet Infection is a cyberpunk RPG for 4 players and a Master, inspired by John Harper's Lady Blackbird, based on mechanics vaguely resembling Vincent Baker's Apocalypse World.
In a few pages, the game contains the background setting, in classic cyberpunk style, the adventure seed, the characters' sheets to play with, and the instruction for the Master. This is all you need for a few sessions of play.
